Kawasaki is issuing a recall on 2008-2011 Ninja ZX-10R and the 2009-2012 Ninja ZX-6R sportbikes due to a defect affecting the batteries.

According to documents released by the National Highway Traffic Safety Administration, the regulator/rectifier on affected units may not sufficiently charge the battery. As a result, the battery may unexpectedly be fully discharged, causing the engine to stall.

The problem is caused by a lack of proper cohesion between the regulator/rectifier’s components. This may lead to overheating of the power module and uncontrolled charging current output.

Kawasaki dealers will replace the voltage regulator on affected units. The campaign affects 20,512 units manufactured between Dec. 14, 2007 and July 26, 2011.
